Chapter 3. Using Cygwin
allows for special cases (such as multiple domains) where the UIDs might match otherwise. The -g
option creates a local user that corresponds to each local group. This is because NT assigns groups file
ownership. The -m option bypasses the current mount table so that, for example, two users who have a
Windows home directory of H: could mount them differently. The -s option omits the NT Security
Identifier (SID). For more information on SIDs, see Section 2.4 in the Cygwin User’s Guide. The -p
option causes mkpasswd to use the specified prefix instead of the account home dir or /home/ . For
example, this command:
Example 3-8. Using an alternate home root
$ mkpasswd -l -p "$(cygpath -H)" > /etc/passwd
would put local users’ home directories in the Windows ’Profiles’ directory. On Win9x machines the -u
option creates an entry for the specified user. On the NT series it restricts the output to that user, greatly
reducing the amount of time it takes in a large domain.

The mount program is used to map your drives and shares onto Cygwin’s simulated POSIX directory
tree, much like as is done by mount commands on typical UNIX systems. Please see Section 3.1.2 for
more information on the concepts behind the Cygwin POSIX file system and strategies for using mounts.
To remove mounts, use umount
